Scorpion was the puppet body of Sasori when he was alive. When he inhabited it, it contained his 'core of living flesh' (生身の核, namami no kaku) in the left compartment in its chest.

On the right side of his chest compartment was a mechanism that could spin numerous chakra threads, which allowed Sasori to use his Red Secret Technique: Performance of a Hundred Puppets. Its stomach contained a thick cable coiled around a pole (which was coated in Sasori's poison before his death), allowing the puppeteer to use it as a stinger and retract it if necessary. Attached to its back was a scroll holder, containing four scrolls that seem to serve as "ammunition", one of which Sasori used to store his puppets. Scorpion also has a pair of poles to the back of its hips, each equipped with five large blades (also drenched in poison) that could spin like propellers, and pipes running through each of its hands that could spew out intense fire or powerful jets of water.
